Poseidon Pressure Washing Service

Its like a shower for your house...

I have been performing pressure washing since I started Poseidon Pools, my swimming pool service company, back in 1970.

I have cleaned pools, decks, fences, houses, sidewalks, commercial buildings, churches, and boats!

I’ve found a method to remove molds, algae, and soil from houses and commercial buildings very efficiently, it’s called “soft washing”. I’m able, with my professional equipment, to apply a diluted, biodegradable solution to the side of houses and buildings, as high as 50 feet from the ground, which chemically removes algae, mold and dirt, and delays the regrowth, but does not harm plants.

I can also kill and remove moss from roofs, which shortens the life of your roof. I can help you remove algae from your home quickly and easily, and avoid fines from your HOA and the embarrassment of green siding on your home.
